Racial and ethnic disparities in metabolic dysfunction-associated steatotic liver disease

Abstract

Metabolic dysfunction-associated steatotic liver disease (MASLD) has an increasing prevalence, morbidity, and mortality both within the U.S. and globally. Here, we review newer evidence demonstrating racial and ethnic disparities that exist in the incidence of MASLD in the U.S. Many studies demonstrate that Hispanic populations have the highest prevalence of MASLD within the U.S., followed by non-Hispanic White populations and then non-Hispanic Black populations. In addition, we present the latest research investigating specific factors that contribute to these disparities, including genetics, environmental exposures, diet, physical activity, and socioeconomic disparities. Finally, we discuss future directions and interventions needed to increase knowledge of racial and ethnic disparities in MASLD and reduce future disparities. The necessary strategies include increasing diversity and documentation of race and ethnicity in MASLD clinical studies, and increased screening and preventative health education for MASLD in vulnerable populations.
